public abstract class PCEPTLV
extends Object

Base class for PCEP TLVs 7.1. PCEP TLV Format A PCEP object may include a set of one or more optional TLVs. All PCEP TLVs have the following format: Type: 2 bytes Length: 2 bytes Value: variable A PCEP object TLV is comprised of 2 bytes for the type, 2 bytes specifying the TLV length, and a value field. The Length field defines the length of the value portion in bytes. The TLV is padded to 4-bytes alignment; padding is not included in the Length field (so a 3-byte value would have a length of 3, but the total size of the TLV would be 8 bytes). Unrecognized TLVs MUST be ignored. IANA management of the PCEP Object TLV type identifier codespace is described in Section 9.
